My Phone had a factory reset and it was in my pocket I have no idea how that happened, is that a SW/HW issue?
How to figure it out?
I got it just two weeks before.
Were you using a PIN/pattern? I guess not.
I had a PIN of 4 numbers, Security for company Email.
Strange,that couldn't have unlocked just like that.Were you using any task killers,antivirus?
Sorry to hear that your phone has been reset.
When using company email (ActiveSync) it's possible to remote wipe the phone from the server and/or Outlook Web Access. I can't say for sure but if you had a PIN-code i suspect it was wiped from the server.
If your company uses management platform like MobileIron it is possible that your phone got wiped that way
Hi and welcome to the community!
Sorry to hear that you've lost all your data 
It's not possible to say for sure but looking at the features for maas360 it has an option for wiping the phone.
I'm afraid it's not possible to restore data that's been deleted on the phones internal storage but you may be able to restore files on the external SD card using a computer, a card reader and a software like Recuva.
If you don't have any backup of the phone i'm afraid what was stored in the internal storage is lost.
You can restore contacts if you saved contacts in Google account.
